I received VA form 21-0538 requesting the status of my dependents.

Hi all, about a month ago I received VA form 21-0538 requesting the status of my dependents. Nothing has changed with my dependents. I have seen post that some people have experience problem with the VA treating this form as a claim. Well, the problem with that is I have a current claim that is getting close to closing and I don’t want them to treat this form as a claim and combine it with my current claim. So my question is should I just sit on the form until my claim is finish? Thanks in advance!
